Description:
------------
It would be great if there was a way to limit the amount of characters that were trimmed from a string, in either ltrim, trim or rtrim, using a new limit parameter.
Reproduce code:
---------------
---
From manual page: function.ltrim
---

I've added a patch (both 5.3 and trunk) for adding a "limit" to the [lr]?trim() functions.
Using a limit of -1 will trim all (same as without adding the limit)
A limit of 0 does nothing (no trimming)
A positive limit will only trim the amount of chars as specified ON BOTH SIDES. This means using a limit of 2 in trim() will strip max 2 chars from the left and max 2 chars from the right:
trim(" hello ", " ", 2) returns " hello ";
ltrim(" hello ", " ", 2) returns " hello ";
The only problem to keep it backwards compatible is that you must add the default charlist ( \n\r\t\v\0) in order to use the limit parameter.
